"Metal box/electronic component with input and output, a switch, a button, and a maybe a knob. Roughly 6.5'"x4.5"x2.5". Broken, but takes a battery. Is this a guitar pedal? If so, any more information? If not, what is it?"
A: "That is a Sovtek Small Stone! They are great distortion pedals made in the mid 90s. Pretty hard to find these days. Someone replaced one of the switches. They came in wooden boxes and are made from Soviet mil-surplus parts or so the legend goes. I still have mine."
